[QUOTE="Geoffc, post: 177780, member: 8705"] Same point. Do you guys think the number or quality of pixels in a jpg differs because of a PPI setting. I'm not bring funny, but the total pixels = pixels wide X pixels high. What do you think these settings actually do in terms of changing the image. Try exporting an image from Lightroom 1000 pixels wide at 72ppi then at 200 ppi. I just did and they are identical in size except the exif has different ppi/dpi values. I've been meaning to do a post on this subject for a while as I think it is often misrepresented. I only started this one as I wondered if I'd misunderstood something and so far I believe my understanding still stands. I would be grateful if someone could post example images of the above settings where it does demonstrate a difference. [/QUOTE]
